Isolation

Momento Cache isolates workloads at the Capacity Pool boundary. A pool is dedicated to your account and does not share capacity with other tenants, so there are no cross-tenant noisy neighbors at the pool level.

Isolation is per pool, not per database

Databases on the same pool share that pool's compute and memory. They are therefore subject to noisy-neighbor effects from each other. A Database that drives heavy load can affect others on the same pool.

Plan your layout accordingly:

• Put workloads that must have sufficient resources onto dedicated pools.
• Pack workloads that tolerate sharing onto one pool to use its capacity efficiently.

Guidance

• Use a dedicated pool for a latency-sensitive or business-critical workload.
• Group development, test, and low-traffic workloads onto a shared pool to control cost.
• Size a shared pool for the sum of its Databases' peaks, with headroom.
